Find out in a minute and a half about how we all start out as female with this awesome science video.

You may have heard this idea once or twice already depending on how much biology you took in school, but this video from AsapSCIENCE goes a level deeper into the awesomeness.

It explains with sharpies and clay how in fetal development the X chromosome starts out dominant, and then the Y chromosome eventually takes over and alters your body’s development (including a shift in your genitals).

As the video notes, most researchers call it the “gender neutral” phase. Even after birth boys and girls are not very different, many of the identifying differences don’t show up until puberty. Boys and girls act differently, but they are also treated and raised differently since the day they are born. It’s rather depressing to see people scream “female privilege!!!!” right here. I agree that female privilege is a problem, one that most gender activists are not help with. However it seems really irrelevant to this video. I’m sure evolution has come up with a number of mechanisms to keep… Read more »

QuantumInc “As the video notes, most researchers call it the “gender neutral” phase.” Well, no, the video states “some prefer to call this stage gender neutral”. Which “some” prefer female, and which prefer neutral? This site prefers female. Scientist prefer neutral – and for good reason. “Even after birth boys and girls are not very different, many of the identifying differences don’t show up until puberty. ” Only if you insist on ignoring the masculinization of the brain in utero. “Boys and girls act differently, but they are also treated and raised differently since the day they are born.” This… Read more »

You don’t need equal numbers of males n females, so no, evolution hasn’t. There are more females worldwide, the only balancer is that some cultures prefer male kids so females get killed. Wartime though reduces the number of men significantly in some wars, ie when they use to go kill off ALL males of the opposing faction n take the women. 1 man can impregnate hundreds of women or more so there is no need for equal numbers especially when today we have welfare, baby formula, much better safety etc so the benefits of a 2 parent relationship aren’t as… Read more »

Well, Dudette – pleased to learn this, since I can now blame deviancy on my mutant genetic inheritance.

You possessors of true genetic purity are fortunate to be

“in point of fact, a particularly haughty and exclusive person, of pre-Adamite ancestral descent. You will understand this when I tell you that I can trace my ancestry back to a protoplasmal primordial atomic globule. I can’t help it. I was born sneering. But I struggle hard to overcome this defect. I mortify my pride continually”

There’s real bad news from the womb for male humans. Once the sex can be established, male embryos are slightly more common than female ones, but male embryos have higher rates of miscarriage, which leads to slightly more female babies born than males, despite the males’ early advantage. This calls into question the overall assumption that males are stronger than females. The time in the uterus says otherwise.

In utero, early in the pregnancy, it’s the most basic form of female privilege at work, not male privilege….

strength differs via age. Before puberty there is no major difference in strength musclewise, after puberty men get more testosterone and more muscle mass, plus better bone structure suited to lifting heavy weights (mostly with the hips n knees, females get more injuries lifting). But women have stronger immunity so what is strength defined by really?
